How many attendees are at a convention if 150 of the attendees are neither female nor students, one-sixth of the attendees are female students, two-thirds of the attendees are female, and one-third of the attendees are students?

900

Explanation:

Let x be no. of attendees.

No. of students = x/3

No. of female students = x/6 = (1/2)(x/3) = (1/2) no. of students

This implies (1/2) of students are male. So,

No of male students = (1/2)(x/3) = x/6     eq (1)

No. of female attendees = 2x/3

No of male attendees = x - (2x/3) = x/3   ...eq (2)

Using eq(1) and eq(2)

No of male non-student attendees = (x/3) - (x/6) = x/6   eq(3)

No of male non-student attendees= 150 (Given in question)  eq(4)

Using eq(3) and eq(4)

=>   x/6=150

=>   x=150*6

=>    x=900 (Answer)

a variable of array type holds a reference of object

array are commonly used in computer program to organize data so that a related set of values

array are using zero base indexing it start with 0.

all component of array have same type, two different types doesn't use in single array

if array are store 10 quantities its index value varies from 0 to 9.

it stores 1st quantity value in index value 0 and this process will same till index value 9.

the answer is gallery.
